Suspension for you car is the same...the only diffrence is that the spring rates and revalve rates of the Struts are more agressive so you may have a slightly harsher ride.
I know, as i ordered directly form germany Sachs struts, which they use on the ST220...mechanicly everything should be the same...but i am only familar with the suspension aspect of the ST220..the mechanical i ahve never done research on.
